shopify functions discount conflicts with code

The actual problem

Shopify Functions automatic discounts fight with discount codes — carts underprice or reject valid codes.

Do this

1. Reproduce code + automatic discount on a kit SKU.
2. Set combination rules intentionally; remove legacy Script Editor leftovers.
3. Export orders with both discount types; flag margin outliers.
4. Freeze Function deploys during major promo weekends.
